The lateral posterior cruciate ligament, also called the posterior cruciate ligament (back of the joint), is part of the intra-articular apparatus of the joints and plays an important role in providing stability to the anterior part of the knee joint. A healthy ligament is attached from one medial epicondyle of the femur to one lateral intercondylar fossa of the leg. Its connection provides significant inhibition of rotational stabilization, preventing excessive rotation of the femur relative to the knee. The joint prevents hyperextension of the knee, especially when rising from a deep flexion position. If it is damaged, the joint can undergo significant subluxation, which leads to disability in patients.
The ligamentous structure of the posterior cruciate ligament consists of a tendon surrounded by a capsule, fibrous membranes, and supporting connective tissue fibers. The femoral head is another fulcrum for the ligament, which connects it into a biaxial ring with other ligaments, including the anterior cruciate ligament. As stated above, this is critical to preventing extension and displacement of the femoral and tibial joint elements relative to each other, which gives stability to the knee. Disruptions to this structure can result in loss of function of this body element, either alone as a cause of injury or in combination with a number of other factors to keep the patient from recovering from injury.
The posterior cruciate ligament is one of the main elements of the mechanism of injury to the intra-articular system. Typically, the most common symptom before it is a sprain or microscopic tear with minor damage and pain during exercise. Although physical testing can be helpful, it cannot replace the use of ultrasonography of the knee to check for damage or evaluate response to treatment. Ultrasonography allows visualization of a violation of the integrity of the ligament. Sometimes a defective echo of the posterior joint can be seen, which can cause other signs of damage, such as damage to the edge of the articular surface, degenerative changes in the bone, or pathological processes in other periarticular elements. Patients with a torn posterior cruciate (PCL) should be treated with caution and joint stability and articular mechanism should be assessed to determine appropriate treatment. However, when recovery is equal to severe acute pain and constant persistent pain, it is reasonable to assume that the injury is likely causing severe lateral displacement of the joint due to inadequate fixation. In this case, rehabilitation simply consists of physical therapy, which should reduce pain. Rest, cold, anti-inflammatory drugs and physical therapy are indicated. Patients with rupture l. The cross should give a prognosis for complete recovery only in the case of a full diagnosis.
